Step 4: Wind bobbin

Scrolling to the bottom of the design table spreadsheet will reveal a number of wire guage choices. Hopefully, one of these will work with your amplifier.

Wind the magnet wire onto the bobbin. With either a lathe or a bobbin winding machine. Try to keep relatively constant tension on the wire as you wind the coil.

Wrap electrical tape around the finished windings or pot in epoxy.
